Greenhouse Gas Emissions

It’s been 8 years in the making, but Washington State finally has a rule that places limits on carbon pollution from its largest sources. It comes in response to reduction targets on greenhouse gas emissions first called for by the legislature in 2008. Starting next year, regulators at the Department of Ecology are requiring large industrial emitters to gradually reduce their carbon emissions over time. The rule will cover industries including power plants, oil refineries, fuel distributors, pulp and paper mills and others.

Rice is a staple in many people’s diets. But you may not know that rice paddies are one of the biggest sources of global methane emissions — a potent greenhouse gas. Now, researchers have found a way to nearly eliminate methane emissions from rice paddies.

When it comes to greenhouse gases, methane is a major contributor to climate change. It is 20 times more efficient at trapping heat than carbon dioxide.

Researchers estimate that up to 15 percent of global human-caused methane emissions comes from growing rice.

The administration of Washington Governor Jay Inslee has officially begun a rulemaking to cap greenhouse gas pollution from large industrial sources. Inslee is flexing his executive powers to bypass the state legislature, which has repeatedly chosen not to put a price on carbon.
